Set Avalibility

[Bluenote20]

Is there standard length of time that a expansion is available in stores or does it vary by expansion and how long is it? Been away from paper magic for awhile and am curious.

I believe that whatever is legal in standard is still being printed.  I'm not 100% though.

[MacUser001]

Only the most recent set is ever printed. But there is still availability of the last two sets or so, if you're lucky.
